From Science Node, Feb. 17, 2016: Einstein predicted gravitational waves over 100 years ago. Resources provided by the Open Science Grid, of which Fermilab is an active member, are helping LIGO prove he was right.

On the road to the world’s largest neutrino detector, take the “DUNE Buggy.”

From The New York Times, Feb. 11, 2016: A team of scientists announced on Thursday that they had heard and recorded the sound of two black holes colliding a billion light-years away, a fleeting chirp that fulfilled the last prediction of Einstein’s general theory of relativity.

The experiment confirms the last piece of Einstein’s general theory of relativity.

A possible explanation for the lightness of neutrinos could help answer some big questions about the universe.

From University of Chicago, Jan. 26, 2016: Argonne, Fermilab and the University of Chicago are among the dozen institutions that are working on upgrading the South Pole Telescope. Scientists are getting ready to install a new camera on the telescope later this year to plumb the earliest history of the cosmos.
